Tecnosky Laser de collimation pour Newton (1.25")

No matter which exact model you have, collimation will take only a few minutes. The laser will also help you to check within seconds whether your Newtonian is still properly collimated. Just insert it into the focuser, switch it on and you'll know precisely whether you need to recollimate the telescope!

The Advantages of the TS LA:

-- rigid all-metal design. Once collimated the laser will not lose its collimation. Not a simple plastic unit!

-- the laser diode can be collimated. If the laser loses collimation due to serious outside influences you will easily be able to align it again.

-- Comfortable 45° side viewing port

-- long 1.25" barrel and broad flange for perfect position of the laser inside the focuser of the telescope.

-- on/off trigger

Using the Laser Collimator in "Fast" Focal Ratio Newtonians

Fast Newtonian telescopes usually have a secondary mirror offset. This means that the secondary mirror is not perfectly in the center, but a few millimeters away from the focuser and towards the primary mirror. The offset is used so that the telescope illuminates the field of view more evenly. This offset makes collimation with classical collimation eyepieces (e.g. Chesire) difficult. A laser collimator does not have any problem with offset, so collimation is much easier with the laser.

An Important Improvement .... the 45° rear view port:



The 45° angled view port allows you to see the collimation progress from the rear of the telescope. Even large Newtonians can thus be easily collimated by a single person.

A Short Manual - How To Use The TS Laser Collimator:

Step 1: Preparation
We recommend to turn the telescope so that the focuser will face up. Then you insert the laser without using the locking screws of your focuser. The laser will then sit on its CNC machined edge.

Step 2: Collimation of Secondary Mirror
After checking the orientation of the secondary mirror with your unaided eye just insert the laser collimator. Then use the collimation screws of the secondary mirror until the laser dot is centered on the primary mirror. A center marking is recommended for this.



Step 3: Primary Mirror Collimation
Turn the laser collimator so that you can see inside the 45° angled view port from the rear end of the telescope. Then use the primary mirror collimation screws until the returning laser dot hits the center of the laser.
